Which has the lowest boiling point NH3 PH3 AsH3 BiH3?

Which has the lowest boiling point NH3 PH3 AsH3 BiH3?

Out of NH3, PH3 and AsH3 boiling point of NH3 is maximum and that of PH3 is minimum.

Which one of the following has highest dipole moment 1 NH3 2 PH3 3 SbH3 4 AsH3?

SbH3, AsH3, NH3, PH3. NH3 would have highest dipole moment. Nitrogen being more electronegative than P, As, Sb, leads to greater bond dipole moment and hence the total dipole moment is also Higher.

Which of the following has the highest bond angle a NH3 B PH3 C AsH3 D SbH3?

NH3 has bond angle of 107°and PH3 and AsH3 possesses respectively bond angle of 93° and 91°.

Which is stronger base NH3 or AsH3?

the strongest base should be NH3 because N is smallest in size and is able to make more stable sigma bond …

Which has highest boiling point NH3 PH3?

NH3 molecules makes strong intermolecular H bonding b/w themselves. But due to lesser electronegativity of larger PH3 molecules, they cannot form Hydrogen Bonding b/w themselves. In NH3, there is hydrogen bonding whereas in PH3 there is no hydrogen bonding. Therefore, the NH3 has higher boiling point than PH3.

Which of the following has highest boiling point NH3 PH3 AsH3?

Answer: From the question NH3 will have highest boiling point among the following since the NH3 has the ability to form hydrogen bonds.

Does AsH3 have a dipole moment?

The molecule of Arsine or Arsenic trihydride (with tetrahedral shape AsH3 molecular geometry) is tilted at 92 degrees. As a result, it has a permanent dipole moment in its molecular structure. The AsH3 molecule has a dipole moment due to an unequal charge distribution of negative and positive charges.

Which out of NH3 and PH3 has higher dipole moment?

NH3 is more basic than PH3 as NH3 has more density of eletron. Owing it to the small size of nitrogen and small P orbitals it has ability to form stronger bond due to effective overlap. However in PH3 the larger sixe of P results in the P orbitals becoming diffuse and preventing effective overlap.

Which of the following has largest bond angle NH3 PH3?

The bond angle in NH3 is larger than, in PH3 because the P−H bonds are longer and the lower electronegativity of P permits electron-density to be displaced towards hydrogen to a greater extent than in the case of NH3.

Which has higher boiling point NH3 or BiH3?

Is AsH3 stronger than PH3?

Arsenic, being farther down on the Periodic Table than Phosphorus, has more electrons that may group together and form instantaneous dipoles. We can say that AsH3 has a higher boiling point than PH3 because arsenic has a higher polarizability than phosphorus.

Does NH3 have a higher boiling point than PH3?

Ammonia, NH3, has a much higher boiling point than phosphine, PH3. NH3 can hydrogen bond, PH3 cannot.

What is the boiling point of NH3 at different temperatures?

Bp of NH3: -33°C, PH3: -87°C, AsH3: -62.4°C, SbH3: -18°C So the increasing order of boiling point is PH3 The regular trend for boiling point is that it increases down the group due to increase in size and van der waal forces between atoms.But the B.p of ammonia (NH3) is more than Ph3 and Ash3

Which of the V group hydrides has the lowest boiling point?

Explanation : Due to the absence of H-bonding, PH3 has the lowest b.p. The boiling point of the V group hydrides is : BiH3> SbH3> NH3> AsH3 > PH3 Please log inor registerto add a comment.

Why does the boiling point of ammonia increase down the group?

The regular trend for boiling point is that it increases down the group due to increase in size and van der waal forces between atoms.But the B.p of ammonia (NH3) is more than Ph3 and Ash3 due to Hydrogen bonding in liquid state.The B.p of SbH3 is still higher due to high extent of van der waal forces.
